4:51 p.m.: A Federal law enforcement official has confirmed that the 34-year-old female driver is deceased, and that the child accompanying her appears uninjured. CNN reports that the first encounter with the suspect began when a uniformed Secret Service agent encountered the woman near the White House in a black sedan. Words were exchanged between the two. The driver initially ignored demands to turn away, but then sped off. The suspect then allegedly hit a police car near Capitol Hill, injuring the officer inside and triggering the airbag. After a use of force was authorized, multiple shots were then fired.
4:06 p.m.: Capitol Police Chief Kim Dine claims that the driver is in custody, not dead, but would not disclose her condition. Senate Sergeant at Arms Terrance Gainer told the AP that a woman was driving the car and had a child, who was taken to a hospital. Many sources are now claiming that shots were not fired by the suspect but came from police instead.
Several witnesses claim that the suspect rammed the gates of the White House, which ignited the pursuit by police, and that a dozen shots were fired. Another version is that she was she told to move her vehicle away from the White House gates by D.C. police, she hit a police car and discharged the car's airbag.
3:45 p.m.: At about 2 p.m. today, shots were fired in Washington, D.C., sparking a brief lockdown of the Capitol. Details are still emerging, but according to police officials, the incident began after a vehicle attempted to pass a barricade near the White House. Shots were then "potentially fired" by the female suspect, and a chase of the vehicle began. A police officer was injured in a crash that ensued. The chase ended near the Capitol, where the suspect's vehicle crashed into a barricade.
In a news conference held a short while ago, officials declined to comment on the condition of the suspect, but several sources are reporting that she was killed in the incident. Some sources are also reporting that a child was removed from the suspect's vehicle. Police officials did note, however, that they believe this is an isolated incident, and not related to terrorism.
